Hint: PERHAPS this is why butterfly males are "prettier" than females, as well as why they have a penchant for using perfumes to entice the opposite sex....

It seems like the answer should be obvious, but if I answer then I become IT - and I've got no idea whatsoever what to ask then! So I'll just shut up... :redface: Or at least try to... :redface:

Isn't it that the sexual chromosomal pairings of butterflies are the exact opposite of humans; i.e. males are homogametic (they have two of the same gametes, represented by ZZ) and females are heterogametic (they have one of each, i.e. ZW)?

Bingo! The male/female chromosome pattern in butterflies is exactly the opposite of humans: Humans:male=XY and females=XX;
Butterflies:male=XX and females=XY.

onewithnature go for it!

:thumbs_up: Africat.

Name two ways in which the colours on butterfly wings are produced.

Colors are produced either by 1. pigments produced by chemical substances in the scales that absorb certain wavelengths of light and transmit the remaining. Red is an example of this, and these colors will fade over time in a collection.

2. structural color - the scales themselves do not contain pigment, but the surface configuration changes light by diffraction and diffusion (like prisms). Blues and metallic colors are examples of this type and as the structure of the scale is inherent, these colors do not fade over time.

Spot on, Africat. :clap: :clap:

To add, the melanistic colours that you mentioned in point 1. usually include browns and black.

YOU'RE IT! :thumbs_up:

Chastity Belts.

The males of what African family have incorporated a version of this concept into their mating habits? Explain how the utilization of this phenomena benefits them.

(I am only looking for the Family, not genus or species.)

It prevents a second, third ... male coming by and also mating with the female ... It is in the form of a horny plug. And some butterflies of the genus Acreae use this.

In some other insects the male remain attached to the female for long periods of time to prevent a second mating.

"... horny plug", Imberbe? :shock: That opens up the possibilities, eh? :wink:

Horny plug...heh, heh...

For those more scientifically oriented (which leaves me out), it's called a sphragis and is a seal or physical block to further matings, insuring the success of his genes in at least this mating.

Imberbe....You 'da Man!
